Abstract

In this paper, the dual-channel optocoupler and current conveyors are employed to achieve the wide bandwidth isolation amplifier. The high gain feedback technique and pole-zero compensation are applied to overcome the inherent nonlinear characteristics of optocouplers and to obtain a good transient response. Its bandwidth is up to 563 kHz and the output response exhibits linear transfer characteristics. The mathematical model of proposed isolation amplifier is propsed. The dynamic responses and static characteristics are also demonstrated with experimental results.
